Yes, that is very good. I DLed 365 or 385 strapless at about 160-165. I think both. Funny thing is, I graduated to straps (which most people on here will advise against) and have done 405, but now I can't even do 275 for more than a couple of reps without straps.
Grip strength is not my priority, back strength and thickness is. So train your priority.
